i using metadata extractor extract metadata image file , working flawlessly until today morning today encountered exception 

java.lang.classnotfoundexception : com.adobe.xmp.xmpexception

and control of web application redirected error.jsp expected

also found article resolve exception

but code extract wrapped in try-catch block why exception didn't catched in catch block

entire stack trace :

caused by: java.lang.noclassdeffounderror: com/adobe/xmp/xmpexception         @ com.drew.imaging.jpeg.jpegmetadatareader.extractmetadatafromjpegsegmentreader(jpegmetadatareader.java:112)         @ com.drew.imaging.jpeg.jpegmetadatareader.readmetadata(jpegmetadatareader.java:71)         @ com.drew.imaging.imagemetadatareader.readmetadata(imagemetadatareader.java:108)         @ com.drew.imaging.imagemetadatareader.readmetadata(imagemetadatareader.java:95)         @ mypackagename.myclassname.readlocationexifdata(myclassname.java:274)

relevant code :

try{     metadata metadata = imagemetadatareader.readmetadata(file); --> line 274     gpsdirectory directory = metadata.getdirectory(gpsdirectory.class);     gpsdescriptor descriptor = new gpsdescriptor(directory); } catch(exception e){ e.printstacktrace(); return null; }
